Nintendo have announced that Pokemon Sword and Pokemon Shield will be the sole focus of the next Nintendo Direct which should provide quite a bit of either new information or new gameplay since the show will last for about 15 minutes.
Pokemon Sword and Pokemon Shield will get a pile of new information on 5 June 2019 when the next Nintendo Direct lands. Unlike the usual Directs, this one will focus only on these two upcoming Pokemon games.
According to the official Twitter post, it will go on for about 15 minutes and will be streamed on the official Nintendo channel on YouTube. You can click the bell button so YouTube reminds you before the show starts - it was about eight days away at the time of writing so it could be easy to forget. Here is a link to the stream.
Nintendo did not divulge what information or gameplay they will show during Pokemon Direct but some of that information might pop up on Pokemon Company's press conference that will be hosted on Twitch. You can follow that event on the official Pokemon website or the official Pokemon Twitch channel.
Keep in mind that Nintendo Direct talking about Pokemon Sword and Shield will go live at 6:00 AM PDT / 1:00 PM UTC on 5 June 2019 while the opposite will work for Pokemon Company press conference which will be available on 28 May 2019 at 6:00 PM PDT / 29 May 2019 at 1:00 AM UTC.
Interestingly enough Pokemon Direct will air in just under a week from E3 2019, where Nintendo already confirmed their presence. This hints at some juicy information on the Direct that could hype people up to warrant a visit during the expo.
However, if the rumours of The Witcher 3 coming to Nintendo Switch turn out to be true, it could take some wind out of Pokemon's sails. It still sounds a bit off though - does Switch have the necessary hardware to run the game that once gave high-end PCs regular nightmares?
